Explain the difference between HTTP and HTTPS.答案：HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting data over the internet. It is not secure, meaning that the data being transmitted can be intercepted and read by anyone. HTTPS (Hypertext Transfer Protocol Secure), on the other hand, is a secure version of HTTP. It uses encryption to ensure that data is encrypted before transmission, making it much more difficult for hackers to intercept and read. HTTPS is commonly used for secure online transactions, such as submitting credit card information or personal details.四、编程题请编写一个Python程序，实现计算圆的面积和周长的功能。

These activities may involve the development of software from scratch in a standard programming language like Java or C. Increasingly, however, new software is developed by extending and modifying existing systems and by configuring and integrating off-the-shelf software or system components.Software processes are complex and, like all intellectual and creative processes, rely on people making decisions and judgments. Because of the need for judgment andcreativity, attempts to automate software processes have met with limited success. Computer-aided software engineering (CASE) tools can support some process activities. However, there is no possibility, at least in the next few years, of more extensive automation where software takes over creative design from the engineers involved in the software process.Although there are many software processes, some fundamental activities are common to all software processes:1). Software specification The functionality of the software and constraints on its operation must be defined.2). Software design and implement-ation The software to meet the specification must be produced.3). Software validation The software must be validated to ensure that it does what the customer wants.4). Software evolution The software must evolve to meet changing customer Needs. Although there is no ‘ideal’ software process, there is scope for improving the software process in many organizations. Processes may include outdated techniques or may not take advantage of the best practice in industrial software engineering. Indeed, many organizations still do not take advantage of software engineering methods in their software development.(1)、A software process is _______.•product•standard programming language•existing system正确答案：B(2)、Software processes ___________.•complex and intellectual enough to be developed byComputer-aided software engineering (CASE) tools.•rely on Computer-aided software engineering(CASE) tools.•depend on the people making decisions and judg ments正确答案：A(3)、software processes usually include ________ activities.•••正确答案：C(4)、Improving the software process in many organizations is ______.•••正确答案：D(5)、Software design and implementat-ion means that _________.•functionality of the software and constraints on its o peration must be defined.•software must be validated to ensure that it does w hat the customer wants.•software must evolve to meet changing customer Ne eds.正确答案：B。

《计算机专业英语》考试题A
Test of Special English for Computer Science《计算机专业英语》考试题A一、写出下列计算机专有名词的中文名. (20%)CPU: RAM:DNS: USBLAN: SMTP:URL: WAN:FTP: HTTP:二、阅读理解.（50%）1 本题20分, 阅读下面的短文,回答下列问题.[1] High-level languages (HLL) allow programmers to express algorithms more concisely, take care of much of detail, and often support naturally the use of the structured programming or objected-oriented design.[2] Alas, this solution gave rise of a problem, known as the semantic gap, the difference between the operations provided in HLLs and those provided in computer architecture. Symptoms of this gap are alleged to include exection inefficiency, excessive machine program size, and compiler complexity. Designers of traditional CISC (Complex Instruction Set Computer) machines responded with architectures intended to close this gap. Key features include large instruction sets, dozens of addressing modes, and various HLL statements implemented in hardware.Please answer the following questions (1) – (3) in English:(1)Which functions are there for HLL in the computer according to paragraph[1]?(5分)(2)What is the meaning of “the semantic gap”in the paragraph [2] ? (7分)(3)Please explain which important features there are in CISC machine in orderto reduce this gap? (8分)2 本题10分, 阅读下面的短文,回答下列问题.[3]A major challenge is hence the harmonization of parallel machine architectures, compilers, and the programming languages, with the goal of allowing programs to be written in high-level, problem-oriented languages, while developing compilers that translate the programs into efficient target code for a wide variety of parallel architectures. Success will be measured by how well real, machine-independent application programs will execute on real, parallel computers. Since highly parallel machines with thousands and tens of processors are already being manufactured and used commercially, this challenge requires a solution urgently.Please answer the following questions (4) – (5) in English:(4)Please explain what is the the goal is in paragraph [3]? (5分)(5)Please explain what the urgent solution needed by the challenge is inparagraph [3]. (5分)3. 本题20分, 阅读下面的短文,回答下列问题.[4]Many embedded system s require predictable and bounded responses to real-world events. Such “real-time”systems include factory automation, data acquisition and control systems, audio/video applications, and many other computerized products and devices. What’s a “real-time system”? The commonly accepted definition of “real-time”performance is that real-world events must be responded to within a defined, predicable, and relatively short time interval.[5]Although Linux is not a real-time operating system (the Linux kernel does not provide the required event prioritization and preemption functions), there are currently several add-on options available that can bring real-time capabilities to Linux-based systems.The most common method is the dual-kernel approach. Using this approach, a general purpose (non-real-time) OS runs as a task under a real-time kernel. The general purpose OS provides functions such as disk read/write. LAN/communications, serial/parallel I/O, system initialization, memory management, etc., while the real-time kernel handles real-world event processing. Y ou might think of this as a “have your cake and eat it too”strategy, because it can preserve the benefits of a popular general purpose OS, while adding the capabilities of a real-time OS.Please answer the following questions (6) – (8) in English:(6)Is embedded system“real-time” system according to paragraph [4]? (5分)(7) Is Linux “real-time”OS?And how does Linux provide “real-time”capabilities? (8分)(8) Which functions are there in the general purpose OS? (7分)三、把下面的短文译为中文.（30%）1. 把下面这段[6]英文翻译成中文. (15分)[6]Polymorphism gives objects the ability to respond to messages from routines when the object’s exact type is not known. In C++ this ability is a result of late binding. With late binding, the addresses are determined dynamically at run time, rather than statically at compile time, as in traditional compiler languages. This static (fixed) method is often called early binding. Function names are replaced with memory addresses. Y ou accomplish late binding by using virtual functions. Virtual functions are defined in the parent class when subsequent derived classes will overload the function by redefining the function’s implementation. When you use virtual functions, messages are passed as a pointer that points to the object instead of directly to the object.2. 把下面这段[7]英文翻译成中文. (15分)[7] A long term goal could be to develop interactive program transformation systems that assist programmers in parallelizing programs and provide feedback and guidance. The problem with this idea is that the approach of semiautomatic program transformations is still an object of active research, even for sequential programs. In the medium term, a production-quality transformer for deriving realistic, parallel programs is unlikely to appear. The traditional method of teaching algorithms and formulating them in programming languages with explicit parallelism is likely to be more successful, especially since the body of known parallel algorithm is large and growing rapidly. Initial indications seem to be that writing parallel software is not significantly harder than writing sequential software, provided the languages and support tools are adequate.。

If you want to solve the computational problem with a computer, you should learn how to program. The task of developing programs for the solution of computational problems is referred to as programming. Computer programming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficult to work out otherwise . So programming is breaking a task down into small steps.Programming is sometimes contrasted with coding. Coding generally refers to the writing of programs for given program specification, while programming includes the task of preparing the program specification as well as that of writing the program. The text of a program is sometimes referred to as code, and lines of program text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications prepared by others.What's actually involved in programming - the actual process of writing programs? Here's a quick overview of the process:·Write a program. ·Compile the program. ·Run the program. ·Debug the program. ·Repeat the whole process until the program is finished.1．If you want to solve the computational problem with a computer, you should learn how to .A. calculateB. programC. addD. subtract2. Computer programming is the process of planning and creating a sequence of for a computer to follow.A. stepsB. processC. linesD. graphics3.

Debug the program.C. Print the program.D. Compile the program.五、Translate the following sentences into Chinese.（本大题共6小题，每小题5分，共30分)1. The program, which tells the computers what to do and the data, which provide the information needed to solve the problem, are kept inside the computer in a place called memory.2. In a big mainframe computer the processor is called a Central Processing Unit, or CPU, while in a microcomputer, it is usually known as a microprocessor.3. The memory unit is an essential component in any digit computer since it is needed for storing the programs that are executed by the CPU.4. At the beginning of each instruction cycle, the CPU fetches an instruction from memory.5. It is very easy to set up a memory system that consists of a single chip.6. If we are going to say that a given program thinks like a human, we must have some way of determining how humans think.六、Translate the following paragraph into Chinese.（20分)Definitions of artificial intelligence vary along two main dimensions. One is concerned with thought processes and reasoning, the other addresses behavior. Also, some definitions measure success in terms of human performance, whereas the others measure against an ideal concept of intelligence, which we will call rationality. A system is rational if it does the right thing. All this gives us four possible goals pursue in artificial intelligence: system that like humans, systems that think rationally, system that act like humans and systems that act rationally.。

There are 3 levels of programming languages, they are __________________, which can be run directly by computer; __________________and______________. There are different high-level programming languages. Fortunately, most of them have many kinds of construct in common and vary only in the way that these must be__________________ . Therefore, first thing to be decided about a task is to choose which programming language is best suited for the job.Passage AThe central processing unit (CUP) is the heart of the computer systems. Among other things, its configuration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, which its speed and capacity have increased tremendously. Indeed, these changes have resulted in micro-Computers that are small enough to fit on your desk and your lap.The CPU comprise the control unit and the arithmetic/logic unit (ALU).The control unit is responsible for directing and coordinating most of the computer systems activities. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical(comparison) functions—that is, it adds, subtracts, multiplies, divides, and does comparison. These comparisons, which are basically “less than”, “greater than”, and “equal to”, can be combined into several common expressions, such as “greater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.(二) Tell whether the following statements are true(T) or false(F) according to the passage A(根据上文的内容判断下列句子的正误) (15%)1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( )2. The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input/output devices are controlled by the control unit of the CPU. ( )3. The CPU comprises the control unit and memory. ( )4. The control unit performs all the arithmetic and logical functions. ( )5. The central processing unit (CPU) is the heart of the computer systems.
